TANK simian;

T aZZ whom it may concern .1

Be it known-that .1, WILLIAM RINE, a CllllZBIl, of the United States, residing at Philadelphia, inthe county'of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Tank Siphons, of which the followingis aspecificationt; I

'Ihe :inve11tion relates to water distribution and more particularly to devices for controlling the flows oroutflow of fluids 2 0" tank reaches a certain point, Various adfrom. a. tank or reservoir'and has for an object; to provide a siphon valve for siphoning a quantity Among other features the invention comprehen'ds-a siphon'valve which after being initially set in operation, will siphon a quantity-of fluid from the tank and destroy the siphon when the level of the fluid inthe j ustments being provided for the adaptation of-thevalvefto various forms and kinds of flush tank devices and appliances.

In the further disclosure of the invention,

referenceisto be hadtothe accompanying drawings, constituting a part of this speci-' fication in which similar characters of referencedenotelcorresponding parts in allthe views and in which,--

' Figure 1' is a sectional view taken through a tank or reservoir showing my device applied thereto, parts being broken I provide a tank '10 having a' suitable inlet pipe 11 thereto, which is controlled by a. valve 12 including a rod and ball structure 13, the latter beingadaptedto rise and fall with the level of the fluid 14 in the tank 10 to open or closethe valve 12 as the case may be, thus determining the level of the fluid in the tank.

My particular "device comprises a body 15;

of fluid from the fluid containin Specification of Letters Patent. Patented Feb; '7, 1922. Application filed November 3, 1919. Serial No. 335,284.

which is formed' to provide a long leg ;16 and a short leg 17 the latter being, enlarged position and reposing against a stop lug 23 struck from the frame 21, the upward swinging movement of the vane 22 being limited by a stop lug 24, projecting from a bail 25 forming apart of the frame 21. The vane 22, together with the frame 21 is adaptedfor vertical movement within thecompartment 1S and normally tends to close the lower end of the; compartment and which being filled with water, will result in the contents of the compartment being raised to pass into 7 the long leg 16 when thelifting-member 20 is actuated. The lifting member includes avertical stem 26 which preferably has a threaded portion 27, the lower end of the stem being rigidly secured to the bail 25 with a closure 28 threaded on to thethreaded portion27; and therefore adj ust-able vertically onithe stenrfor a purpose that will be hereinafter more fully disclosed. The upper portion ofthe stem projects loosely througha vertical tubular guide 29 which secured to the upper portion "ofthe short leg. 17 and: depends within the compartment 18, the upper extremity of the stem 26 carrying a closure and stop element 30v which -normally reposes upon the top of the guide '29, limiting the downward movement of'the lifting member in the compartment 18 and alsotightly fitting the top of the guide to act as a, closure therefor. In a similar manner when the lift ng member is pulled up wardly, the closure 28 bears against, the lower depending end of the guide to close the same, theiupper endof the guideatthis time being open by reason of the raising of the stem 26. With this construction; one end of the guide 29 and what might also be termed a pipe; is closed when the lifting member is in its lowered position and the lower end of'the pipe is closed when the lifting member is in its uppermost position.

Mounted to swing on a projecting stud 31 carried by the body 15, is an adjusting arm vided a depending pipe 37.xvhich extends 32, intermediate portionsof which'are provided with cross apertures 33, the free extremity of the arm having connected'thereto, one end of a rod 84, the upper end-of downwardly to have its lower end connectwiththe adjusting arm 32 through one of J the apertures 33. 7

At substantially the juncture of the long leg 16'with' the short leg 17, there is pro downwardly to within a short distance of the bottom of the tank, said pipe being provided to break the siphon as will be hereinafter set out in explaining the'operation of the device.

Now assuming that water 14, when it is desired tocremovev a quantity of the water from the tank to;

have the same flow through. the outlet pipe 19, a pull is exerted on the pull handle 35,

thus exerting an upward pull onthe rod l 36, andwhich in turn will cause the adjusting the lifting member 20 and the quantity of water contained "in the compartment1'8,

' with sulficient force to ca-use'the water to flow upwardly around the curved portion 7 at the juncture of the long and short leg 1G, 17, and into the long leg 16 through which-the water will fiow to the outlet pipe j 19, and as will be apparent :a-siphon will be created so that the water contained in the tank will continue to flow up -through the shortened leg 17 and down through the long leg 16,the upward flow-of the water through the compartment 18 holding the vane 22 in a' sub a opentposition' 'Now when the level of wate'rin' the tank reaches a point below the lower end of the pipe 37, the inrush of air throughthe pipe 37 tothe interior of the bodyc15, will break the siphon,'causing the vane 22 to return to its closed horizontal position, and the valve 12 now being open because of the lower position of the ball float or rod and ball structure, a new supply of water will be received through the pi e 11, to again I fill the tank tothe require level. Now it will be seen that when the device is in the position shown in Figure 1, the closure '30 I V siphon.

the tank is filled with ing arm 32 to be swung upwardly thus raiswill close the upper end of: theguidelpipe 29, acting'also as a stop to limit the. downward move'meiit of the lifting member and when i an' upward pull is exerted on the handle 35, the closure 28 engaging against the lower'end' of the guidepipe cwill close' the sam'e preventing any inrus'h of air 7 through the 'guide 'pipe and which would tend to destroy the very suction ,which it, is desired to create in order to prolong the By providing theadjusting arm 32 and the jconnection'b'etween thefadjusting arm 170 and the pull and between the adjusting arm and the lifting member, I allow for an ad justment of theconnection' between the pull and thearm becausefof the differencein the strokes of different; forms of pull handles and thus it will be apparent that with my form of device the same can bejemploye'd in connection withvari'ous kinds ofoperat ing levers or the like and an'adjustment 'madeYbetween the operating lever-or device and' the lifting member whereby the desired length of stroke to: accomplish the desired purpose can be arranged for, through the. medium, of the adj usting" arm having the cross apertures '33 for the accomf modation of the lower end of the rod i361 Although I have shown a particular form of my invention in the drawing anddescribed the same in detail in this specifica 'tion, it will be understood that various. slight changes may be made from the construction set out without departing from the spirit of the invention,- the scopefof which is defined in the appended claim.

' -Having described my inventi0n,I claim 7 A tank si hon comprising an inverted U-shaped b'ocy including along leg leading to an outletfand further including a formed rectangular in cross-section, an open rectangular frame slidably mounted within said chamber, a bail securedto said frame, a vertically swinging vane pivoted within said frame, stops for limiting 'upward and downward swinging of the vane,

a tubular guide extend-ing vertically within said chamber, a stem sli'dable through said guide and connected rwith said bail, and

short leg enlarged to define 'a chamber members mounted on the stem above andbelow .theguide and engageable therewith limiting movement ofgthe-frame'i j 1 In testimony whereof I afiix" my signature.
